Clarkson allegedly called Oisin "a lazy, Irish c***" while threatening to have him sacked before splitting his lip.

Four days after the incident it is understood panicking Clarkson went around to Oisin's house to apologise but he did not answer. Clarkson then telephoned the BBC's director of television Danny Cohen to tell him about the hotel "fracas" earlier that week.

Clarkson was then suspended on March 10 pending a BBC investigation.

Two weeks later the BBC announced it would not renew his contract.

Director-general Tony Hall said at the time: "A line has been crossed."

The star received widespread public support - including that of his friend Prime Minister David Cameron - in the aftermath of the fracas.

Over one million people signed a petition calling for his reinstatement.

He was already on a final warning with the BBC after a string of Top Gear controversies - including mumbling the N-word in unseen footage exclusively revealed by the Mirror.

BBC director general Tony Hall confirmed Oisin attended A&E after the attack and described Clarkson's "sustained and prolonged verbal abuse of an extreme nature".

Oisin, 36, who shares his North London flat with his girlfriend, received death threats from Clarkson fans but refused to press charges.

After routine inquiries North Yorkshire Police confirmed Clarkson will face no further action.

It is estimated Clarkson's sacking could cost the BBC £62 million.

He may still fulfil plans to appear on stage with former colleagues Richard Hammond and James May in live Top Gear shows later this year.

But the gigs will be stripped of all BBC branding and content, and they'll be billed as Clarkson, Hammond and May Live.

Although his Top Gear contract wasn't renewed, he has not been banned from appearing on the BBC altogether.

It comes a day after we reported he had pulled out of hosting BBC's Have I Got News For You later this month.

He was due as a guest presenter on the satirical news quiz, with team captains Ian Hislop and Paul Merton, in what would have been his first Beeb appearance since his sacking.

Jimmy Mulville, managing director of Hat Trick Productions which makes the programme, said: "We fully expect him to resume his hosting duties later in the year."

Clarkson cannot take Top Gear to Netflix with him, as the BBC own the rights to the show.

But recent reports have suggested the American TV and film streaming service are keen to sign him up for a similar car show.

They have the financial clout to offer him a big money deal and because the new show - dubbed Top Gear 2.0 - would be streamed and not aired on TV, he could have full control and would be less restricted in terms or what he could say.

Last year Netflix announced it had over 3 million users in the UK, thanks to shows like House of Cards and Breaking Bad. Users pay a monthlysubscription.

Auctioning off a T-Shirt from the show, Clarkson said: "This was from a programme called Top Gear."

In response to an audience reaction he said: "It will be back, just somewhere else," before adding cryptically: "Or maybe not, who knows."

In a dig at his former BBC bosses he branded the Welsh town of Tenby "a wonderful place despite the country it's in".

He added: "They used to be able to sack me for that kind of thing but they can't now!" At the end of the night, before he was whisked away in a black Mercedes.

Clarkson told the audience: "Thank you very much for coming to see an unemployed man."
